Application July 20, 1955, Serial No. 523,312

8 Claims. (Cl. 132-31) My invention relates to a hair-curling device of the type shown in my U. S. Letters Patent No. 2,652,063, dated September 15, 1953.

My device comprises a flexible rod and a wrapper folded about it forming two flaps, a tube within which the flexible rod is seated, the flaps extending outwardly through a slot in the tube, the tube also seating a key the rotation of which causes the tube to rotate, thus winding the tress of hair between the flaps around the tube, on completion of which the wrapping is partially secured to the tube by bending back the outer projecting end of the flexible rod, the key is withdrawn, and the other end of the projecting rod is bent back against the tube which remains within the wrapping until the curl has set.

The device disclosed herein has several important advantages over my said prior device, including the following:

Its use uniformly produces tight and neat curls;

It permits a full set of the tubes, one for each curl to be formed, to be assembled in advance of the curling operation, with the flexible rod properly mounted therein, with the Wrapper extending through the slot of the tube, and the flexible rod adjusted in its seat to a snug fit against the slot, eliminating any further adjustment of the rod or the wrapper, thereby greatly facilitating the task of forming the curls.

The cost of its manufacture is materially less than that of my said prior device.

It is an object of my invention to provide a haircurling device which insures the uniform production of well formed, tight and neat curls.

It is a further object of my invention to provide such a hair-curling device which will enable the pre-assembly of the tubes about which the curls will be formed and the flexible rods and wrappers used therewith.

It is a further object of my invention to provide such a hair-curling device which is more economical in cost.

Referring to the drawings:

A is a flexible rod. A flexible plastic tube having a flexible wire center 5, is suitable. A wrapper B comprising a strip of thin paper or other suitable flexible material to absorb the liquid applied to the hair in order to maintain the form of the curls, is folded about rod A, forming two opposed flaps 14, 15, one of which is preferably longer than the other for ease in separating them. C is a tube of circular or other suitable cross-section, made of a resilient plastic or other suitable material. A seat 20 for rod A extends through tube C and a seat 30 for key D extends through tube C.

Slot 21 extending lengthwise of tube C is cut through the outer wall of seat 20 normal to the axis of seat 20 to accommodate flaps 14, 15 of wrapper B when rod A and wrapper B folded about it are inserted in tube C.

Seat 20 is arcuate in cross-section, forming slightly more than a semi-circle, having a diameter approximately equal to the diameter of rod A, providing a sliding fit therewith. The entrance 24 of seat 20 is slightly less than its diameter for the purpose later explained. Seat 20 has shoulders 25, with slightly rounded corners.

Key D comprises a shank 31 and a handle 32. Shank 31 is a rod, incompletely circular in cross-section, as shown in the drawings, but may be of other suitable cross-section. Key D may be made of plastic or other suitable material, with shank 31 and handle 32 formed integrally or detachably.

An arcuate groove 40 extends lengthwise of shank 31 having shoulders 41 which are opposed to shoulders 25 of seat 20 and engage therewith when key D is rotated, shoulders 41 and 25 preventing relative rotation of shank 31 and tube C.

Rod A with its folded wrapper B is initially inserted in seat 30 before key D is inserted therein, flaps 14, 15 extending through slot 21, as shown in Fig. 4. After rod A is so inserted, an upward pull on flaps 14, 15 will snap rod A into seat 20, due to the resilience of tube C, wherein it will be held snugly, as shown in Fig. 5.

Groove 40 in shank 31 enables shank 31 to clear the portion of rod A which protrudes from seat 20, when shank 31 is inserted in seat 39.

Handle 32, as shown, has a cylindrical portion 33 and hexagonal portion 34. Slot 45 extends through handle 32.

Rod A is longer than the width of wrapper B, its ends 12 protruding from the fold of wrapper B' about it, the outer end protruding from tube C and the inner end entering slot 45 of handle 32.

Sides 46 of slot 45 diverge upwardly towards and to the top of handle 32, slot 45 extending longitudinally for the length of projecting end 12 of rod A.

Slot 45 of handle 32 provides space for a distortion of rod A, resulting from its prior bending in use of the device.

The use of the hair-curling device disclosed herein is simple.

As a preliminary step, the user assembles a set of tubes 3 C," one for each curl, usually 32in number, with rods A and their wrappers to be inserted therein. First, wrapper Bis folded about rod A, making two flaps 14, 15, one longer than the other. Rod A with its said fold of wrapper B is then inserted in key seat 30 of tube C, flaps 14, passing through slot 21. After this insertion, shown in Fig. 4, is completed, flaps 14, 15 are given an upward pull, which'snaps rod A and its fold'o'f' wrapper B into close engagement with the sides of seat and slot 21, where it is snugly held without need for any further adjustment, as shown in Fig. 5. After tubes C, rods A and wrapper B have thus been assembled, shank 31 of key Dis inserted inseat of a tube C, flaps 14, 15 are separated, the tress of hair 50 selected for the curl to be formed is inserted between them which are manually held together while tube C is rotated by key D sufliciently to secure them to tube C, the rotation then continuing until the wraper and tress are completely wound around tube C Without further manual holding. When the winding 'iscompleted, the outer projecting end of rod A is bent back; partially securing the wrapping to tube C, key D is Withdrawn from tube C, the other end of rod A is bent back, fully securing the wrapping to tube C which is left in place within the curl.

This operation is continued successively with the tube assemblies until all curls have been formed. After the curls have been set, tube C, rod A and Wrapper B are Withdrawn from the curls, and are disassembled, the wrapper being discarded.

Modifications and changes of the embodiment shown may be made without departing fromthe invention.
